Description

Приборы, предназначенные дл  11сн 1тани  различных огнеупорных материалов, нагреваемых в олектронечи н нагружаемых уснлием с;катн  л процессе нагрева, известны.Devices intended for the use of various refractory materials heated in electrical systems and loaded with heating; the heating process is known.

Недостатком этих нрнборов  вл етс  ограннчеиный темнературный предел нх нрнмененн  (1800-2000°), вследствие того что точность )гоказаний прибора зависзи от термического расширени  частей лрибора , весьма значительного нри высоких температурах нагрева.The disadvantage of these houses is the limited temperature limit of them not exceeding 1800-2000 °, due to the fact that the accuracy of the instrument depends on the thermal expansion of the parts of the lab very high heating temperatures.

В описываемом нриборе отсутствует этот н:одостаток. Конструкци  измерительной части ирнбора устран ет jsoBMOH-CHOCTb погрешностей в иоказа:1Г1г х прибора, вызываемых тепловым расширением чаете прнбора в процессе пзмерепий.This nribore is missing this n: one thing. The design of the measuring part of the irborder eliminates jsoBMOH-CHOCTb errors in indications: 1G1g x of the instrument caused by thermal expansion of the equipment in the process of specimen.

На чертеже дана приидипнальна  схема прибора.In the drawing, a typical device diagram is given.

Нрлбор выполнен в виде двух вертикалыгых стержней 1 и 2, изготовлен гглх пз материала с одинаковым коэффицпетгтом температуртгого )ас П11репт1  и уетапа ливаемых на дне электрической печн 3 с Г1)афитовым или вольфрамовым сопротивлением.The nrlbor is made in the form of two vertical rods 1 and 2, made of material with the same coefficient of temperature and temperature P11rept and installed at the bottom of the electric furnace 3 with G1) with afit or tungsten resistance.

Оержень 2 может неремендатьс  но вертпр-;алн в :гаправл юп1,пх 6 и скреплен верхнпм своим концом с неравномерно градунрованнот ткапоп 1. На верхнем конце стернлн  укреплена o/uia из двух осей указательной стрелкп 8, фикспрующей вертпкальпое неремегцение стержн  } нроцессе деформацпи иснытуемого образца.(ter / kep 2 with a graphite tip at the lower end, irarpy load 4, rests on a sample of 5 pshytym material installed on a graphite attachment at the bottom of an electric furnace. upper end with unevenly graded mcapop 1. At the upper end of the stern, the o / uia is reinforced from two axes of the index arrow 8, which fixes the vertical movement of the rod during the deformation process of the specimen.

In the upper part of this rod, the BTOfian index axis is fixed.

Такое устройство измерительной части прибора не требует впедеден   в показани  прибора поправок па темнературпое расширение частей прибора в процессе нагрева испытуемого образца, так как градуированна  шкала перемещаетс  вместе с вертикальным стержнем, опирающимс  на образец.Such a device of the measuring part of the device does not require the correction of the parts of the device during the heating of the test sample, as the graduated scale moves with the vertical rod resting on the sample.

Предмет изобретени Subject invention

Прибор дл  измерени  деформации огнеунориых материалов под нагрузкой при высокой температуре с нримеиением вертикальной электропечи дл  нагрева испытуемого образца, отлпчающийс  тем, что, с целью устранени  иогрешностей, завис п1;их от термического расширении частей прибора, измерительное устройство укреилено на выполненных из материалов с. одинаковым коэффициентом термического расптнреии  двух стержи х. одни из которых опираетс  на нсиытуемый образец, а второй па ту же опору, что и образец.A device for measuring the deformation of flammable materials under load at a high temperature with the use of a vertical electric furnace for heating a test specimen, which is dependent on the thermal expansion of the parts of the device to eliminate errors, the measuring device is made on materials made of materials the same thermal expansion coefficient of two rods x. one of which is based on the designated sample, and the second one the same support as the sample.
